According to various embodiments, the processor may be configured to determine whether the force touch is changed, and, when the force touch is not changed, the processor is configured to execute a first function by means of the system button, and, when the force touch is changed, to execute a second function by means of the system button.

FIGS. 2A and 2B are views illustrating a system button in an electronic device according to various embodiments of the present disclosure.

Referring to FIGS. 2A and 2B, FIG. 2A illustrates an example in which a systems button (or system key) 210, 220, 230 of a system button region 200 is displayed along with a first screen (for example, an application execution screen) through the display 131 of the electronic device 100, and FIG. 2B illustrates an example in which the system button 210, 220, 230 of the system button region 200 is transparent and thus is not displayed, or is displayed translucently through the display 131 of the electronic device 100, and a second screen (for example, an application execution screen) is displayed as a full screen through the entire region of the display 131.

In various embodiments, the system button region 200 is a touch region which is allocated the system button 210, 220, 230, and may be implemented independently from an application execution screen (for example, as a separate layer), and may provide the system button 210, 220, 230.

In various embodiments, the system button 210, 220, 230 may indicate one or more buttons (or keys) for executing a system function which is set to be operated by a user operation at any time even while various operations of the electronic device 100 are being executed, for example, set to be globally operated. In various embodiments, the system button 210, 220, 230 may be a software button and may be displayed through the display 131 of the electronic device 100.

According to various embodiments, the system button 210, 220, 230 may include, for example, a first button 210 for a system function of viewing a recent list, a second button 220 for a system function of returning to the home screen, or a third button 230 for a system function of returning to a previous screen. However, the present disclosure is not limited thereto, and the system button or the system function thereof may be implemented variously and complexly.

According to various embodiments, the first screen or the second screen may include a screen (for example, a UI, a GUI) executed by various applications installed in the electronic device 100 and executable and displayable. In various embodiments, the application may include an application for the home screen, an application for a menu screen, respective applications for various contents (for example, a game, a video, a digital broadcast, etc.), a gallery application, an application for photographing, a message application, or the like, and the first screen or the second screen may indicate a screen corresponding to an executed application.

According to various embodiments, the execution screen of the application may be displayed by separating (or dividing) the system button region 200 and the first screen (for example, an application execution screen) as shown in FIG. 2A, or by superimposing the system button region 200 on the application execution screen in an overlay method (for example, displaying a partial screen). For example, the first screen of the application and the system button 210, 220, 230 of the system button region 200 are displayed altogether as shown in FIG. 2A. In this case, a system function (for example, viewing a recent list, returning to the home screen, or returning to a previous screen) may be immediately executed according to a user input by means of the system button region 200 where the system button 210, 220, 230 is located.

According to various embodiments, to prevent the execution screen of the application from being covered, the system button 210, 220, 230 of the system button region 200 may be displayed on the display 131 transparently or translucently, and the second screen (for example, an application execution screen) may be displayed as a full screen by using the entire region as shown in FIG. 2B. According to various embodiments, when the system button 210, 220, 230 of the system button region 200 is provided transparently or translucently, the system button may not operate by a normal input (for example, a touch), and may operate by an input which is set to operate the system button (for example, a force touch).

According to an embodiment, an execution screen of an application (for example, a video play application, a game application, or the like) operating based on the full screen may be displayed through the entire region of the display 131, and the system button 210, 220, 230 of the system button region 200 may be processed transparently and may not be displayed on the display 131. According to another embodiment, when the execution screen of the application operating based on the full screen is displayed, the system button 210, 220, 230 of the system button region 220 may be provided translucently.

According to various embodiments, the system button 210, 220, 230 may be hidden from the display 131 by a user operation or automatically (for example, with reference to time). According to an embodiment, in a state as shown in FIG. 2A, the system button 210, 220, 230 may be activated (shown)/inactivated (hidden) according to an input for hiding the system button 210, 220, 230. For example, the user may select (touch) a specific location (for example, a hiding button) of the system button region 200, or may perform a user input operation (for example, dragging, flicking, or the like) of moving to a bezel portion 250 of a lower end of the display 131 while holding selection (touch) on a specific location (for example, an empty region) of the system button region 200. In response to the user input, the electronic device 100 may process hiding not to display the system button 210, 220, 230 on the display 131. To the contrary, the system button 210, 220, 230 that is not displayed on the screen may be processed to be displayed on the display 131 by the inverse operation of the above-described user input operation (for example, a user input operation of entering the screen from the bezel portion 250 of the lower end of the display 131).

In various embodiments, as shown in FIG. 2B, an execution screen related to a specific operation (for example, executing an application, entering a specific screen, etc.) may be displayed through the entire region of the display 131 (for example, displaying a full screen), without displaying the system button 210, 220, 230.

According to various embodiments, a system function related to the system button 210, 220, 230 may be enabled to be used according to a user input even when the system button 210, 220, 230 is not displayed. For example, according to various embodiments, the electronic device 100 may distinguish a user input (for example, a force touch, a touch) while displaying an execution screen related to a specific operation on a full screen, and may enable a function related to the hidden system button 210, 220, 230, or a function related to the executed specific operation to be controlled more simply and more easily according to a user input. That is, in various embodiments, the system button 210, 220, 230 may be enabled to be always manipulated (for example, to execute a system function) even when the system button 210, 220, 230 disappears.

According to an embodiment, even when the system button 210, 220, 230 is not displayed as shown in FIG. 2B, if a user presses a location where the system button 210, 220, 230 has been located using a force (for example, a force input), a force signal related to the system button 210, 220, 230 may be transmitted and the system button 210, 220, 230 may operate, and a system function related to the corresponding system button may be executed. In addition, in various embodiments, by touching a location where the system button 210, 220, 230 has been located, a touch signal associated with the execution screen of the application may be transmitted, and a function related to the application may be executed. According to various embodiments, since the force signal and the touch signal are distinguished, the system function and the application-associated function may be independently processed, without colliding with each other, according to a user input on an overlapping region (for example, a location of the system button region 200) between the system button 210, 220, 230 and the execution screen of the application, while the system button 210, 220, 230 is hidden.

Hereinafter, a specific operation of distinguishing a user input on the hidden system button region 200, and processing a system function or an application-associated function based on the distinguished user input according to various embodiments will be described.

FIG. 3 is a flowchart illustrating an operating method of an electronic device according to various embodiments of the present disclosure.

Referring to FIG. 3, in operation 301, the controller 180 (for example, a processor) of the electronic device 100 may display an execution screen. When a user input (operation) for executing a specific application is detected, the controller 180 may execute the corresponding application. According to various embodiments, the application may include various applications which are installed in the electronic device and are executable and displayable, such as an application for the home screen, an application for a menu screen, respective applications for various contents (for example, a game, a video, digital broadcasting, or the like), a gallery application, an application for photographing, a message application, or the like. In response to the application being executed, the controller 180 may control to display the execution screen (for example, a UI, a GUI) related to the executed application through the display 131. According to various embodiments, the controller 180 may provide the system button 210, 220, 230 transparently or translucently when displaying the execution screen of the application. According to an embodiment, the controller 180 may hide the system button to prevent the execution screen from being covered, and may not display the system button on the display 131.

In operation 303, the controller 180 may detect a user input by means of the system button region 200. For example, the controller 180 may distinguish between an input by means of the system button region 200 and an input by means of another region, based on a location on the touch screen 130 that is touched by a user's finger. According to an embodiment, a user may touch the system button region 200 to perform an operation associated with the application (for example, selecting an icon, selecting a link, etc.) or to perform an operation (for example, a system function) associated with the system button 210, 220, 230 on the execution screen of the application.

In operation 305, the controller 180 may distinguish the user input. For example, when the user input on the system button region 200 is detected, the controller 180 may determine whether the use input corresponds to a first input (for example, a force touch) or a second input (for example, a touch). According to an embodiment, the controller 180 may detect a first sensing value by the touch detector 133, and then may detect a second sensing value by the force detector 135 according to one user input (for example, a change in the type of input, touch input→force input). The controller 180 may identify the user input as the first input (for example, the force touch) based on the second sensing value. According to an embodiment, the controller 180 may detect only the first sensing value by the touch detector 133 according to a user input (for example, a touch input, not a force input). When the second sensing value is not detected after the first sensing value is detected, the controller 180 may identify the user input as the second input (for example, the touch) based on the first sensing value.

When it is determined that the user input is the first input (for example, the force touch) in operation 305, the controller 180 may process a system function by means of the system button 210, 220, or 230 in operation 307. For example, the controller 180 may control to execute a system function (for example, viewing a recent list, returning to the home screen, or returning to a previous screen) set for the system button 210, 220, or 230 of a location where the user input is detected by the touch detector 133, and to display a corresponding screen through the display 131.

When it is determined that the user input is the second input in operation 305, the controller 180 may process an application function by means of the application in operation 309. For example, the controller 180 may control to recognize an object (for example, a link, an icon, a menu, a function button, or the like) of the location where the user input is detected by the touch detector 133, to execute an application-related function associated with the object in response to the user input, and to display a corresponding screen through the display 131.

FIG. 4 is a flowchart illustrating an operating method of a system button in an electronic device according to various embodiments of the present disclosure.

Referring to FIG. 4, in operation 401, the controller 180 (for example, a processor) of the electronic device 100 may execute an application. According to various embodiments, the application may include various applications which are installed in the electronic device 100 and are executable and displayable. The controller 180 may determine (detect) an execution mode (for example, a full screen mode) of the application corresponding to a user's operation.

In operation 403, the controller 180 may determine whether the executed application is using a full screen mode or not. For example, when the execution of the application is detected, the controller 180 may determine an execution mode (or state) of the application, based on whether the corresponding application is executing a mode for operating on a full screen of the display 131 (for example, a mode in which the system button is processed transparently and is not displayed on the screen, or is processed translucently and is displayed, and the screen of the application is displayed on the full screen), or whether the corresponding application displays a certain region (for example, the system button region 200) set to include the system button, and operates on a partial screen of the display 131. In various embodiments, the partial screen may be an execution screen of the application that is distinguished (divided) from the system button region 200, or may include a screen that is displayed by superimposing the system button region 200 on the execution screen of the application in an overlay method.

When the execution mode of the executed application is not based on the full screen, that is, based on the partial screen, in operation 403 (No in operation 403), the controller 180 may display the execution screen of the application on the partial screen in operation 407. For example, the controller 180 may control to display the execution screen of the application and the system button 210, 220, 230 by means of the system button region 200 on the display 131 altogether.

In operation 409, the controller 180 may determine whether to toggle to the full screen. For example, the controller 180 may determine whether there is a request for hiding the system button 210, 220, 230 displayed on the system button region. According to various embodiments, the system button 210, 220, 230 may be activated (shown)/inactivated (hidden) based on various inputs. For example, as described above, the user may perform a user input operation of selecting (touching) the system button region 200 and moving to a bezel portion of a lower end of the display 131 (for example, dragging, flicking, or the like). In response to the user input, the controller 180 may hide the system button 210, 220, 230 not to be displayed on the display 131. To the contrary, the system button 210, 220, 230 may be processed to be displayed on the screen by the inverse operation (for example, a user input operation of entering the screen from the bezel portion of the lower end of the display 131) of the user input operation on the undisplayed system button 210, 220, 230 described above.

When toggling to the full screen is not detected in operation 409 (No in operation 409), the controller 180 proceeds to operation 407 to perform operations after operation 407.

When toggling to the full screen is detected in operation 409 (Yes in operation 409), the controller 180 proceeds to operation 405 to perform operations after operation 405.

When the execution mode of the executed application is based on the full screen in operation 403 (Yes in operation 403), the controller 180 may display the execution screen of the application on the full screen in operation 405. For example, the controller 180 may process to display the execution screen of the application through the entire region of the display 131, without displaying the system button 210, 220, 230 through the system button region 200 (for example, by hiding the system button).

In operation 411, the controller 180 may detect a user input by means of the system button region 200. The controller 180 may distinguish between an input by means of the system button region 200 and an input by means of another region, based on a location on the touch screen 130 that is touched by a user's finger. According to an embodiment, a user may touch the system button region 200 to perform an operation associated with the application (for example, selecting an icon, selecting a link, etc.) or to perform an operation (for example, a system function) associated with the system button 210, 220, 230 on the execution screen of the application.

In operation 413, the controller 160 determine a type of the user input, and in operation 415, may determine whether the user input corresponds to a force touch or a touch. For example, when the system button 210, 220, 230 is not displayed, and a user input is detected through a certain region (or coordinates) of the system button region 200 where the system button 210, 220, 230 is located, the controller 180 may determine whether the corresponding user input is inputted as a force touch or a normal touch. According to an embodiment, the controller 180 may detect a first sensing value by the touch detector 133, and then may detect a second sensing value by the force detector 135 according to one user input (for example, touch input→force input). The controller 180 may determine the user input as a force touch based on the second sensing value. According to an embodiment, the controller 180 may detect only the first sensing value by the touch detector 133 according to a user input (for example, a touch input, not a force input). When the second sensing value is not detected after the first sensing value is detected, the controller 180 may determine the user input as a normal touch based on the first sensing value.

When it is determined that the user input is a force touch in operation 415 (Yes in operation 415), the controller 180 may determine to process an operation by means of a system button in response to the user input in operation 417. For example, the controller 180 may determine to execute a system function corresponding to the system button according to the user input.

In operation 419, the controller 180 may identify the system button of the region (location, coordinates) corresponding to the user input. For example, the controller 180 may determine the system button 210, 220, or 230 of the location where the user input is detected by the touch detector 133, or a system function corresponding to the system button.

In operation 421, the controller 180 may process the system function corresponding to the system button. For example, the controller 180 may control to execute the system function (for example, viewing a recent list, returning to the home screen, or returning a previous screen) set according to the system button, and to display a corresponding screen through the display 131. According to various embodiments, when processing the function by the system button, the controller 180 may distinguish an input method of the user input (for example, a force touch, a force long press (or a long press after a force touch) on the system button, and may differently execute the distinguished system function by one system button according to the corresponding input method.

When it is determined that the user input is a touch in operation 415 (No in operation 415), the controller 180 may determine to process an operation by the application in response to the user input in operation 423. For example, the controller 180 may determine to execute an application function associated with the application which is being executed according to the user input.

In operation 425, the controller 180 may distinguish the user input. For example, the controller 180 may identify an object (for example, a link, an icon, a menu, a function button, etc.) of the location where the user input is detected by the touch detector 133, and also, may distinguish an input method of the user input (for example, a touch, a drag, a long press, etc.).

In operation 427, the controller 180 may process an application function related to the application according to the user input. For example, the controller 180 may control to recognize the object (for example, a link, an icon, a menu, a function button, etc.) of the location where the user input is detected by the touch detector 133, to execute an application-related function associated with the object in response to the user, and to display a corresponding screen through the display 131.

FIG. 5 is a view illustrating an example of an operation performed by distinguishing a user input based on a hidden system button in an electronic device according to various embodiments of the present disclosure.

Referring to FIG. 5, FIG. 5 illustrates an example of operations of distinguishing a user input on the hidden system button region 200, and of executing a system function or an application-associated function based on the distinguished user input.

As shown in example (A) of FIG. 5, example (A) of FIG. 5 illustrates a screen of the electronic device 100 on which an application is executed and an execution screen of the executed application is displayed on a full screen of the display 131. In this case, the system button 210, 220, 230 may be displayed transparently or translucently. According to an embodiment, as shown in example (A) of FIG. 5, a web page may be displayed on the full screen of the display 131. For example, the electronic device 100 may not display the system button 210, 220, 230 through the system button region 200 (for example, hide the system button), and may display the execution screen of the web page through the entire region of the display 131.

In the state as shown in example (A) of FIG. 5, the electronic device 100 may detect a user input by means of the system button region 200. For example, the electronic device 100 may distinguish an input by means of the system button region 200 and an input by means of another region, based on a location of the touch screen 130 that is touched by a user's finger. According to an embodiment, the user may touch the system button region 200 (500) to perform an operation associated with the application (for example, selecting an icon or a link), or to perform an operation (for example, a system function) associated with the system button 210, 220, 230 on the execution screen of the web page.

The electronic device 100 may determine a type of the user input, and may determine whether the user input corresponds to a first input (for example, a force touch), or a second input (for example, a touch). For example, when the system button 210, 220, 230 is not displayed, and the user input 500 is detected through a certain region (or coordinates) of the system button region 200 where the system button 210, 220, 230 has been located, the electronic device 100 may determine whether the corresponding user input is inputted as a force touch or a normal touch.

According to an embodiment, when the electronic device 100 detects a first sensing value by the touch detector 133, and then detects a second sensing value by the force detector 135 according to the user input (for example, a touch input→force input), the electronic device 100 may determine that the touch 500 of the system button region 200 is the first input based on the second sensing value. According to an embodiment, when the electronic device 100 detects only the first sensing value by the touch detector 133 and then does not detect the second sensing value after detecting the first sensing value according to a user input (for example, a touch input, not a force input), the electronic device 100 may determine that the touch 500 of the system button region 200 is the second input based on the first sensing value.

When it is determined that the user input 500 is the first input, the electronic device 100 may identify a system button (for example, the system button 220) of the region (location, coordinates) corresponding to the user input 500. For example, the electronic device 100 may determine the system button 220 of the location where the user input is detected by the touch detector 133, or a system function by the corresponding system button 220. The electronic device 100 may execute the system function (for example, returning to the home screen) corresponding to the system button 220, and may control to display a screen (for example, the home screen) corresponding the system function (for example, returning to the home screen) through the display 131 as shown in example (B) of FIG. 5.

When it is determined that the user input 500 is the second input, the electronic device 100 may identify an object (for example, a link) of the location where the user input is detected by the touch detector 133. The electronic device 100 may process an application function (for example, executing a web page according to the link) related to the application according to the user input 500. For example, the electronic device 100 may control to recognize the object (for example, the link) of the location where the user input is detected by the touch detector 133, to execute an application-related function (for example, a web page according to the link) associated with the object in response to the user input 500, and to display a screen (for example, another web page screen) corresponding the application-related function (for example, the linked web page) through the display 131 as shown in example (C) of FIG. 5.

According to various embodiments, as shown in FIG. 5, when the execution screen is displayed based on the full screen (example (A) of FIG. 5), and the user input 500 on an object of the execution screen, overlapping the system button of the system button region 200, is detected, the electronic device 100 may distinguish the user input, and may process the system function by means of the system button 210, 220, 230 or the application function by means of the object (for example, a link). For example, when the user input 500 is inputted as the first input (for example, a force touch) on the location overlapping the system button 210, 220, 230, the electronic device 100 may execute the system function based on the system button 210, 220, 230 (for example, example (B) of FIG. 5), and, when the user input 500 is inputted as the second input (for example, a touch), the electronic device 100 may execute an application function based on the object (for example, a link) of the application of the corresponding location (for example, example (C) of FIG. 5).

FIG. 6 is a flowchart illustrating an operating method by a hidden system button in an electronic device according to various embodiments of the present disclosure.

Referring to FIG. 6, in operation 601, the controller 180 (for example, a processor) of the electronic device 100 may display an execution screen of an application on a full screen. For example, the controller 180 may process to display the execution screen of the application through the entire region of the display 131, without displaying the system button 210, 220, 230 through the system button region 200 (for example, by hiding).

In operation 603, the controller 180 may detect a user input. For example, a user may touch or do a force touch on a certain region of the execution screen of the application.

In operation 605, the controller 180 may determine whether the user input is a force touch or a touch. According to various embodiments, when detecting the user input, the controller 180 may determine whether the corresponding user input is inputted as a force touch or a normal touch. According to an embodiment, the controller 180 may detect a first sensing value by the touch detector 133 and then may detect a second sensing value by the force detector 135 according to a user input (for example, a change in the type of input, touch input→force input). The controller 180 may determine the user input as the force touch based on the second sensing value. According to an embodiment, the controller 180 may detect only the first sensing value by the touch detector 133 according to a user input (for example, a touch input, not a force input). When the second sensing value is not detected after the first sensing value is detected, the controller 180 may determine the user input as the normal touch based on the first sensing value.

When it is determined that the user input is a touch in operation 605 (No in operation 605), the controller 180 may process a function related to the application in response to the touch in operation 609. According to an embodiment, when the application is a game, the controller 180 may process a first operation related to a game manipulation in response to the user input. According to an embodiment, when the application is a web page, the controller 180 may process a first operation of toggling to an execution screen of another web page related to a link, and displaying the execution screen in response to the user input. According to an embodiment, when the application is a video play application, the controller 180 may process controlling a first function (for example, pause, volume, stop, list display, fast forward, rewind, replay position designation, etc.) related to playing of a corresponding media file (for example, a video, music, etc.) in response to the user input.

When it is determined that the user input is a force touch in operation 605 (Yes in operation 605), the controller 180 may determine a region where the force touch is detected in operation 607, and may determine whether the region for the force touch corresponds to the system button region 200 in operation 611. For example, the controller 180 may distinguish an input by the system button region 200 and an input by means of another region based on the location on the touch screen 130 that is touched by a user's finger.

When it is determined that the user input is the force touch by means of the system button region 200 in operation 611 (Yes in operation 611), the controller 180 may process a system function corresponding to the corresponding system button 210, 220, or 230 of the system button region 200 in operation 613. According to an embodiment, when a force touch by means of the location of the system button 210 is detected, the controller 180 may execute a recent list viewing function set for the system button 210, and may process displaying a screen corresponding thereto (for example, displaying a list of recently executed applications). According to an embodiment, when a force touch by means of the location of the system button 220 is detected, the controller 180 may execute a home screen returning function set for the system button 220, and may process displaying a screen (for example, the home screen) corresponding thereto. According to an embodiment, when a force touch by means of the location of the system button 230 is detected, the controller 180 may execute a previous screen returning function set for the system button 230, and may process displaying a screen (for example, a previous execution screen or another screen according to exit of the application) corresponding thereto.

When it is determined that the user input is not the force touch by means of the system button region 200 in operation 611 (No in operation 611), that is, the user input is a force touch within the execution screen region of the application, the controller 180 may process a function related to the application in response to the force touch in operation 615. According to an embodiment, the controller 180 may process a function different from the function related to the application, performed based on the touch as described above. According to an embodiment, when the application is a game, the controller 180 may process a second operation rather than the first operation related to a game manipulation in response to the user input (force touch). According to an embodiment, when the application is a web page, the controller 180 may process another second operation (for example, copying a link, etc.), rather than toggling to an execution screen of another web page related to a link, in response to the user input (force touch). According to an embodiment, when the application is a video play application, the controller 180 may process controlling a second function (for example, playing a next list) rather than the first function related to playing of the corresponding media file (for example, a video, music, or the like), in response to the user input (force touch).

FIG. 7 is a flowchart illustrating a method for processing functions distinguished by distinguishing user inputs in an electronic device according to various embodiments of the present disclosure.

Referring to FIG. 7, in operation 701, the controller 180 (for example, a processor) of the electronic device 100 may detect a user input through the system button region 200. For example, the controller 180 may distinguish an input by means of the system button region 200 and an input by means of another region based on a location on the touch screen 130 that is touched by a user's finger.

In operation 703, the controller 180 may determine whether the user input is a force touch or a touch. According to an embodiment, when the controller 180 detects a first sensing value by the touch detector 133 and then detects a second sensing value by the force detector 135 according to a user input (for example, touch input→force input), the controller 180 may determine the user input as a force touch. According to an embodiment, when the controller 180 detects the first sensing value by the touch detector 133 and then does not detect the second sensing value according to a user input (for example, a touch input, not a force input), the controller 180 may determine the user input as a touch.

When it is determined that the user input is a force touch in operation 703 (Yes in operation 703), the controller 180 may determine whether the force touch is changed in operation 705. For example, the user may input a force touch and then may move the force touch (for example, moving the force touch while holding the force input (for example, a force drag or a force move), or may release the force input and may move a touch input (for example, a drag or a move). Alternatively, the user may input a force touch and then hold the force touch for more than a predetermined time (for example, a long press while holding the force input (for example, a force long press)), or may release the force input and hold a touch input (long press). The controller 180 may determine a change in the force touch as described above until the force touch is released after detecting the force touch.

When the force touch is not changed in operation 705 (No in operation 705) (for example, the force touch is released after being inputted), the controller 180 may process a first function by the corresponding system button in operation 707. It is assumed that the force touch is released right after the force touch is inputted. According to an embodiment, when the system button on which the force touch is detected is the system button 210 for viewing a recent list, the controller 180 may execute the recent list viewing function in response to the force touch. According to an embodiment, when the system button on which the force touch is detected is the system button 220 for returning to the home screen, the controller 180 may execute the home screen returning function in response to the force touch.

When the force touch is changed in operation 705 (Yes in operation 705), the controller 180 may process a second function by a corresponding system button in operation 709. For example, it is assumed that the change in the force touch is the force long press. According to an embodiment, when the system button on which the force touch is detected is the system button 210 for viewing a recent list, the controller 180 may execute a split screen viewing function, which is a second function of the system button 210, rather than the recent list viewing function, in response to the force touch. According to an embodiment, when the system button on which the force touch is detected is the system button 220 for returning to the home screen, the controller 180 may execute a voice recognition function which is a second function of the system button 220, rather than the home screen returning function, in response to the force touch.

When it is determined that the user input is a touch in operation 703 (No in operation 703), the controller 180 may determine whether the touch is changed in operation 711. For example, the user may input the touch and then may move the touch (for example, a drag or a move). Alternatively, the user may input the touch and then may hold the touch for more than a predetermined time (for example, a long press) The controller 180 may determine a change in the touch as described above until the touch is released after the touch is detected.

When the touch is not changed in operation 711 (No in operation 711) (for example, the touch is released after being inputted), the controller 180 may process a third function associated with an application by the touch in operation 713. For example, it is assumed that the touch is released right after the touch is inputted. According to an embodiment, the controller 180 may identify an object rather than the system button in the region where the touch is detected, and may execute a third function corresponding to the object. According to an embodiment, when the object includes a link, the controller 180 may control to display a web page according to the link. According to an embodiment, when the object is a function button (a photographing button), the controller 180 may control to execute a function (for example, photographing) mapped onto the function button.

When the touch is changed in operation 711 (Yes in operation 711), the controller 180 may process a fourth function associated with the application by the touch in operation 715. For example, it is assumed that the change in the touch is the long press. According to an embodiment, the controller 180 may identify an object rather than the system button in the region where the touch is detected, and may execute the fourth function corresponding to the object. According to an embodiment, when the object includes a link, the controller 180 may control to display an additional option menu (for example, opening a link, opening a new page, copying URL, storing), which is the fourth function, in association with the link, rather than executing a web page. According to an embodiment, when the object is a function button, the controller 180 may control to execute the fourth function (for example, continuous shooting) in association with the function button, rather than executing the third function (for example, shooting) mapped onto the function button.

According to various embodiments as described above, when an execution screen is displayed based on a full screen, and a user input on an object of the execution screen overlapping the system button of the system button region 200 is detected, the electronic device may distinguish the user input and may process a system function by the system button or an application function by the object. For example, when the user input is a force touch on an overlapping location of the system button, the electronic device may execute the system function based on the system button, and, when the user input is inputted as a touch, the electronic device may execute an application function based on the object of the application on the corresponding location. In addition, according to various embodiments, the electronic device may distinguish user input methods (for example, whether the input is changed) regarding the force touch and the touch, and may execute different functions in response to the respective inputs (for example, the force touch, the touch) according to the distinguished user input methods. According to an embodiment, the electronic device may operate by distinguishing between the first function and the second function according to the input method of the force touch, and may operate by distinguishing between the third function and the fourth function according to the input method of the touch.
